I'm pulling my 55gallon in from outside...it will be my sump in a few short days...anyways, I want to reinforce the silicone seals on the sides (the ones on the bottom are still very much present and strong) and I need to clean it, so as to make sure the silicone sticks. Will denatured alcohol (Isopropyl, I believe) be safe to use? I know most (if not all) evaporates, but I wanted to check first. Thanks all.

[edit]It's only been outside for a few weeks, due to lack of space for it inside...just wanted to tell everyone WHY I was crazy enough to have the tank outside in a Michigan winter [/edit]
